The invention discloses a papermaking method capable of improving paper forming strength performance. Calcium silicate filler and fine fibers are compounded with the adoption of acid, compounded filler is added to ground plant fibers, and filling paper is obtained after the mixture is put on a net, formed, pressed and dried. By means of the method, the strength performance of the calcium silicate filling paper can be remarkably improved, and the papermaking method has remarkable advantages in the aspect of development of high-filler paper.
